Application January 5,

3 Claims.

The present invention relates to an improvement in Watch cases, oneobject of which has been to provide a combined watch case, calendar andmemorandum device which can be embodied in a single compact unit withoutsacrificing effective operation of the various parts.

One embodiment of my invention as applied to a wrist watch constructionis illustrated in the drawing accompanying the present specification andin WhiCh-- Figure 1 is a top plan view;

Figure 2, a central longitudinal section;

Figure 3, a plan view of interior structural arrangement;

Figure 4, a view in perspective of a frame or mounting for rollerscarrying a calendar strip or the like, and

Figure an enlarged detail in central longitudinal section of ademountable roller adapted to be inserted into and removed from theframe or support illustrated in Figure 4 and an end portion of aflexible strip.

Referring to the drawing, my improved construction includes a main frameor base 1, upon which is mounted an upper plate or cover 2 to form acasing having an opening 3 in which a crystal 23 is retained.

The base 1, Figure 3, is provided with a partition 4 which forms anannular or other suitably shaped compartment adapted to receive a watchmovement 5, or the like, the winding stem of which extends through aside wall of the base and carries a thumb piece 6 in a convenientposition for manipulation in winding. The main frame or base 1 alsocarries a separate, preferably removable, frame 7 which provides asupport for three parallel rollers 8, 9 and 10. A narrow strip 11 offlexible material suitable for the purpose is mounted on said rollers,as shown more clear- 0 ly in Figure 2, said strip being provided withnumeral markings indicating the days of the month arranged inconventional calendar sequence. Other markings, as capital lettersrepresenting the names of the days of the week, appear on the face plate12 of the watch movement in proper juxtaposition to the numeral markingson strip 11.

The rollers 8, 9 and are preferably of the type shown in Figure 5, eachhaving a longitudinally extending recess 13 in which is mounted aplunger 14 normally maintained in extended position by means of a spring15. The outer end of plunger 14 engages or is journaled in acorresponding bearing or hole 16 in the removable frame 7. Thus, toinsert the roller 10, for ex- 1934, Serial No. 705,347

ample, in operative position, the ends of the plunger 14 are depressedand brought into register with the bearing holes 16 Where they arereleased. To disengage the roller from the frame, the plungers 14 arepressed inwardly until their outer end surfaces disengage the bearingholes 16. The roller may then be displaced and removed in a well knownmanner.

As shown in Figure 5, the rollers 9 and 10 may, if desired, be providedwith a slot 24 adapted to receive end portions 25 of the strip 11 tofacilitate winding thereof on the rollers.

The rollers 9 and 10 are provided with intermeshing pinions 17 and 18respectively. A portion of the teeth of one of said pinions, as 18,extends through a slot 19 in the cover plate 2 sufficiently to permitthe rollers 9 and 10 to be rotated in either direction by manuallyrotating the pinion 18. With this arrangement, it is possible toconveniently advance the strip so as to bring any desired portionthereof or of the calendar or other markings thereon into extendedposition opposite the opening 3 or so as to be visible therethrough. Theface plate 2 is also provided with a surface 20 prepared as byroughening or by a suitable coating to receive pencil or similarmarkings to serve as memoranda, said surface preferably being such thatthe markings may be repeatedly erased without impairing itseffectiveness to receive subsequent markings. A flap or cover 21pivotally mounted at 22 is arranged to conceal and protect the surface20 and also the projecting portion of pinion 18 when in closed position.

From the foregoing description it will be ap- 0 parent that my improvedconstruction whether employed in a wrist watch or in other typesprovides a simple and compact arrangement whereby the wearer or user mayenjoy the convenience of a timepiece, a calendar and a memorandum deviceall combined in a single unit. The arrangement of the calendar strip issuch that it may be removed and replaced from year to year or at suchother times as may be desired or necessary.

I claim:-

1. A watch case having bottom and end walls arranged to form a hollowspace, one end of which is adapted to receive a Watch mechanism having aface plate and the other end to receive a calendar mechanism, atransparent top cover in the two winding rollers are provided withintermeshing pinions, one of which has a peripheral portion extendingthrough said top wall and exposed for manual strip moving operation.

3. A watch case according to claim 1 and wherein the outer surface ofthe top wall is adapted to receive erasable memorandum markings and acover is hinged to the casing in position to conceal said outer surfaceof the top wall when in closed position.
